[毕业设计]双头可调立式钻床设计附论文和caxa版图纸

摘    要

此次设计为可调立式双头钻床的机械设计。设计主要介绍了可调立式双头钻床的设计原理、调整方法及设计计算过程。通过预先给定的加工要求可确定所需的计算参数,进而依据可调立式双头钻床的设计原理来设计计算并校核各个部位的零件,然后进行组装。本次设计可从五大方面进行设计。通过预先给定的加工要求计算并进行了可调式双头钻头的设计、传动系统减速箱的设计、传动系统电机的选用、X-Y工作台的设计、钻头轴向进给系统的设计共五部的设计。通过设计并组装后的钻床可以一次加工两孔,且两钻头间的距离可调,从而实现可以在一个工件上加工多对两两间距不同的孔。在人力和设备不增加的情况下使用可调立式双头钻床可以成倍提高钻床的加工效率,并可以保证较高的加工精度和孔间相对位置精度。

ABSTRACT

The machine design is to devise an adjustable vertical double-headed drilling machine.The design mainly introduced the designprinciple, adjustinganddesign calculation process for devise a adjustable vertical double-headed drilling machine. Through the processing requirements given in advance can determine the computation parameters, then based on the design principle, which is about adjustable vertical double-headed drilling machine, to design ,calculate and check each place parts, and then to assemble all theparts. The design can be devised from five aspects. Through the processing requirements given in advance,five parts of the design, the adjustable double transmission system, design of the reducer drive system for the motor selection, design of X-Y workbench, design of axial feeding system for drill bits, can becalculated and devised. Through design and assembly of the drilling machine, two holes can be formed after one processing, and the distance between the two holes can be adjusted. So as to realize processing somegroups ofholes with different space between two holes. Adjustable vertical two-headed drilling machine canmultiply processing efficiency without increasehuman and equipment, and can guarantee a high machining accuracy and precision of the relative position between holes.

Key words:Ball screw;motor;gearbox;Adjustable two-headed drill bit.
